Are you trying to use the brace with round bits or the square conical ends like Irwin and Jennings brace bits?
One thing to check is that the inside of the chuck housing isn’t scored. If it is, or there is hardendened grease inside, the jaws won’t function well. The jaws open and close by contact with the inside of the chuck housing.
If it is scored, you have some time with the various grades of emery paper in store for you. Work on it until it feels smooth to the touch.
Then use a LIGHT coating of fresh lithium grease.
Also, file any burrs of the slot the jaws fit in.
